Problems solved by technology
[0004] However, autofluorescence imaging technology also has certain limitations. For example, it only obtains black-and-white images or other monochromatic images that can reflect the brightness differences of various regions, and it is difficult to highlight the lesion area; moreover, it is easily affected by the uniformity of illumination. high rate of misdiagnosis

Embodiment Construction
[0063] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0064] Currently, in order to highlight the lesion area and reduce the misdiagnosis rate, the white light image and the autofluorescence image can be fused to obtain a fused image that can more accurately reflect the lesion area. However, the inventors of the present application have found that in clinical applications, there is still a certain rate of misdiagnosis using the above-mentioned fusion imaging technology.
[0065] The reason is that the ...

The invention discloses an image processing method and device applied to an endoscope, image processing equipment and an endoscope system. The method comprises the steps of acquiring a white light image and an autofluorescence image of a subject; carrying out fusion processing on the white light image and the autofluorescence image, and determining an initial recognition region on the basis of theobtained fused image; recognizing an abnormal imaging region on the basis of the white light image and / or the autofluorescence image; and eliminating the abnormal imaging region in the initial recognition region to obtain a target region. Therefore, the white light image and the autofluorescence image can be subjected to fusion processing after being acquired; the initial recognition region is determined according to the fused image; the abnormal imaging region is further recognized on the basis of the white light image and / or the autofluorescence image; and the abnormal imaging region in theinitial recognition region can be eliminated to eliminate the influence of abnormal imaging on diagnosis, thereby effectively reducing the misdiagnosis rate of an endoscope imaging technique.
Description
technical field [0001] The present application relates to the technical field of endoscopes, and more specifically, to an image processing method and device applied to endoscopes, an image processing device, and an endoscope system. Background technique [0002] Gastrointestinal cancer is a common malignant tumor in the human body. Worldwide, an average of about 750,000 people die of gastric cancer every year. In the past 30 years, the annual incidence of esophageal cancer and colorectal cancer in China has also shown an obvious upward trend. Early detection and early diagnosis are the key to improving the clinical treatment effect of cancer. Although digestive endoscopy is considered to be the best method for diagnosing gastrointestinal tumors, small lesions such as early flat tumors and dysplasia are easily missed under ordinary white light endoscopy. [0003] Endoscopic autofluorescence imaging technology is a new highly specific diagnostic technology for gastrointestin...
